i seeing one panel in left side (like sa-4 range finder) so its one moveable system, 100 per 100
You are 100% correct. The 9K33 Osa (SA-8) was designed by the NII-20 bureau under the leadership of V.P. Efremov, right after the 2K11 KRUG (SA-4) system.
Im quite proud, that you could identify a Soviet SAM design bureau just looking at the operation panel!

Greek Osa (from the ex East German Army inventory) is tracking Turkish F-4E Phantom...
